Love it!  I'm always repurposing items.  So, I broke this 6-tiered rolling metal stackable utility cart rack storage organizer trolley into two separate carts consisting of three baskets each.  I use one cart for fruits and vegetables and put the white tray on the last basket with the anti-skid feet.  I use the other cart to organize my mail as follows:  one basket is for incoming mail, the second basket is for bills, and the third basket is to temporarily house mail that I will read or get to later.  It is so versatile that should I need a fourth basket for fruits and vegetables or less baskets for mail, I can always adjust the quantity.  This organizer trolley is great and just what I needed!
